Classifying the nuclear equation of state in LVK interferometric noise through core-collapse supernova gravitational-wave signatures using convolutional neural networks
Alejandro Casallas-Lagos, Marek J. SzczepaÅczyk, Michele Zanolin +4
This paper presents a convolutional neural network (CNN) approach to classifying the nuclear equation of state (EOS). As illustrative examples, we use five two-dimensional core-col…
Joint Detection and Characterization of the Standing Accretion Shock Instability for Core-Collapse Supernovae with cWB XP
Vicente Sierra, Zidu Lin, Michelle Zanolin +3
The most sensitive to-date multimessenger detection of the standing accretion shock instability in real interferometric data is presented, which quantitatively identifies the prese…
Quantification of the parameter estimation error from Rotating Core Collapse supernovae
Claudia Moreno, Javier M. Antelis, Michele Zanolin
In this paper, we perform parameter estimation with an analytical model to simulate the gravitational wave emission during the core bounce phase of a rapidly rotating core collapse…
Bayesian parameter estimation for the Core-bounce phase of Rapidly Rotating Core-Collapse Supernovae in real interferometric data
Emmanuel Avila, Michele Zanolin, Javier M. Antelis +1
We present a novel methodology to estimate the ratio of kinetic to gravitational potential energy in core-collapse supernova progenitors and to assess the equation of state (EOS) u…
Residual neural networks to classify the high frequency emission in core-collapse supernova gravitational waves
Manuel D. Morales, Javier M. Antelis, Claudia Moreno
We present a new methodology to explore the morphology of the High Frequency Feature (HFF), i.e., the dominant, rising-frequency GW emission from a proto-neutron star in core-colla…
On the detectability of gravitational waves emitted from head-on collisions of -boson stars
Mariana Lira, Laura O. Villegas, Javier M. Antelis +3
In this work, we investigate head-on collisions of -boson stars, potential candidates for dark matter compact objects. We begin with a review of the general properties and fe…
